Last year, a record 6.28 million people visited the Met, and the schedule shift was made so the institution would be “accessible whenever visitors have the urge to experience this great museum,” museum director Thomas Campbell said in a statement.

The museums of the Smithsonian Institution are open daily in the United States, and across the pond, London institutions, including the British Museum, the National Museum and the Tate galleries, are open every day.

The Getty Center in Los Angeles and the Getty Villa in Malibu are closed Mondays and Tuesdays, respectively. The Hammer Museum is closed Mondays. The downtown Museum of Contemporary Art for years has maintained a five-day-a-week schedule, (closed Tuesdays and Wednesdays), but there have been rumblings -- and recommendations -- for a change.
